China confirmed conducting a test flight of a new hypersonic missile delivery vehicle capable of delivering nuclear warheads with record breaking speeds. The move is purely scientific and not targeted at any country, said the Defense Ministry.

"Our planned scientific research tests conducted in our
territory are normal," said the Beijing Defense Ministry as
cited by Reuters on Wednesday. "These tests are not targeted
at any country and at any specific goals."

The ministry’s statement confirmed a report by the Washington
Free Beacon on Monday. The newspaper cited US Pentagon officials
saying that a hypersonic glide vehicle (HGV) was detected flying
at ten times the speed of sound over China on January 9.

The officials added that the ultra-high speed missile vehicle is
aimed at "delivering warheads through US missile
defenses."

The HGV dubbed the WU-14 was reportedly designed to be launched
as the final stage of China’s intercontinental ballistic missile.
Its hypersonic speed range reportedly lies between Mach 5 and
Mach 10, or 3,840 to 7,680 miles per hour.

US Congress voiced concerns on Tuesday fearing the country is
falling behind in the international hypersonic arms race.

“While round after round of defense cuts have knocked
America’s technological advantage on its back, the Chinese and
other competitor nations push towards military parity with the
United States; in some cases, as in this one, they appear to be
leaping ahead of us,” Chairman Rep. Howard P. “Buck“ McKeon
(R., Calif.) and Reps. Randy Forbes (R., Va.) and Mike Rogers
(R., Ala.) said in a statement as cited by Washington Free
Beacon.

The newspaper also said the test made China the second country
after the US to have successfully tested a hypersonic delivery
vehicle able to carry nuclear warheads at a speed above Mach 10.

Hypersonic vehicles, designed by the US, Russia and India, are
developed for precise targeting and rapid delivery of weapons.
They are intended to counter hostile missile and space defenses.

Annual increases in China’s military spending have allowed
Beijing to boost the quality and performance of domestic weapons
and military hardware. According to Chinese technical reports
from December 2012 and April 2013 the country is developing
precision guidance systems designed to be directed via satellite.

Russia too has confirmed the development of “a new class of
hypersonic vehicle” that would “allow Russian strategic
missiles to penetrate missile defense systems,” according to
the Air Force National Air and Space Intelligence Center.
